Hey yo,
A book where a young fit male gets dropped off into this testing facility with other fit males and no contact with the outside world.
Every morning, the walls open up and runners have to run and map out the new maze that forms outside the walls. The runners have to get back to base before dark or else the walls will close and they'll disappear/become monsters/be new drug test subjects (can't remember).
New supplies are provided for the group via an elevator — the same one the main character arrived in.
Then a girl shows up, she's pale and pretty. The main character and she discover that they can Mindlink.
By overlaying the maps of the mazes, they figure out a code, and they use it to get out (or something).
Title was Wall Runner or The Runners, maybe.
